+| `show_commit`       | `false`                              | Shows the commit as part of the version.              |
+| `symbol`            | `'Ø '`                               | The symbol used before displaying the version of Zig. |
+| `style`             | `'bold bright-blue'`                 | The style for the module.                             |
+| `disabled`          | `false`                              | Disables the `odin` module.                           |

+| version  | `dev-2024-03` | The version of `odin`                |
+| symbol   |               | Mirrors the value of option `symbol` |
+| style\*  |               | Mirrors the value of option `style`  |
+
+*: This variable can only be used as a part of a style string
+
+### Example
+
+```toml
+# ~/.config/starship.toml
+
+[odin]
